Chlorophyll fluorescence parameters retrieved from MONI-PAM data after Porcar-Castell (2011). Note that the sum of and are here equal to only during nighttime when is equivalent to , but can be also calculated in daytime by using .

Diurnal quenching parameters		Diurnal yield parameters		Seasonal quenching parameters		Seasonal yield parameters
Total Photochemical quenching		Quantum yield of photochemistry		Sustained photochemical quenching		Maximum photochemical efficiency of PSII
Total photochemical quenching (fraction)		Quantum yield of total		Sustained photochemical quenching (fraction)		Quantum yield of sustained NPQ
Total Non-photochemical quenching		Quantum yield of reversible NPQ		Sustained non-photochemical quenching		Quantum yield fluorescence and constitutive thermal energy dissipation (seasonal component)
Reversible non-photochemical quenching		Quantum yield of fluorescence and constitutive thermal energy dissipation
